Listen to Jillius. You absolutely must have more counter between sink and range for prep. Minimum 36". Most prefer closer to 48". I have 54" and wouldn't want to lose as inch. As jannicone stated, that is the "most precious" counter in the kitchen, a natural place for doing all your prep work so you will want to have room to spread out, and not having adequate prep counter there will make cooking in your kitchen very inefficient and frustrating. So, as Jillius said, switch fridge to other end of room, put a microwave, if you are having one, on a shelf next to the fridge, and install drawers for dishes where you currently have the fridge. Then, on the sink side, move the DW all the way to the left (you will probably need 1-2" of filler between DW and wall), move the sink down next to the DW, and enjoy the nice prep space between sink and range every dang time you cook. It looks like this will triple your prep space. Yay! And move your trash into the prep space because that is where most trash is generated. Composting, too, if you do that. These changes will make a huge difference. I would not want to work in your current kitchen plan at all. I would hate it. I would love to work in your kitchen if you make those changes. It will make cooking so much more efficient, efficient and even fun! I probably shouldn't add this but I can't keep my mouth closed sometimes. Your designer is NOT a great designer. Your designer is doing a hack job, focusing on appearances over function when you can have both function and a nice appearance, and is ignoring some of the most basic rules of kitchen design established by the NKBA. Is he/she a member? Just curious.

This is more or less what I do using MS Paint, which anyone with a Windows computer has. If one doesn't, then there are some free "paint" apps available for download. You can cut and paste with it, meaning that if you can find a picture of a plant, you can copy and use it in the drawing. But the trouble with that is "cleaning" the plant from its background can be time consuming. If you have drawing/painting skills, it is much easier to just paint plants into a photograph. The process is much like oil painting. If you make mistakes, but not to many, you can use the "undo" button. If you drew something too long ago and don't want to undo because you drew more recent things that you want to keep, then you must draw over what you don't like. Or paste in a piece of the original photo to bring an area back to the starting point, and then draw on that. I use a touchscreen and a stylus. It's hard to draw detail with a finger on a touchscreen. If you have only a mouse/trackpad you can still draw using line and some other tools, so it will be more limited in what you can do.

https://www.hover.to/  is a startup focused on home remodeling to do exactly what you're looking for. You take 8 pics of your house from an app, and it creates a 3D model of your home where you can change roof color, siding color and material, etc. it worked really well on my old house, not sure if it translates as well to a new homewrap home, but is definitely worth a try. It's a free trial so no risk.
